Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 80mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100B
The ACQJ32X80-100B is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend stroke. With a full stroke of 80 mm and a 100 mm adjustment window, you can fine-tune the usable extend range from 0 to 80 mm directly on your equipment. The retract stroke remains completely unaffected by this mechanism. A male M14x1.5 rod-end thread couples directly to your load.
Because the piston area is unchanged, force output is identical to a standard ACQ of the same bore, delivering 402.1 N push and 301.6 N pull at 0.5 MPa. The cylinder body incorporates sensor grooves for tracking position, though this specific configuration ships without a magnet. Deceleration is handled by a fixed NBR elastomer bumper at each end, rather than an adjustable air cushion.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 80 mm |
| Adjuster thread | M12×1.25 |
| Port size | PT1/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Speed range | 30 – 500 mm/s |
| Rod thread | M8×1.25 (F) / M14×1.5 (B) |
Specifications follow the official AirTAC ACQJ datasheet. The adjustable stop shortens the EXTEND stroke only; the piston area — and therefore the force — is the same as a standard ACQ of this bore. Adjustable window options: 10/20/30/40/50/75/100 mm.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
Force equals a standard ACQ of the same bore — the adjuster changes stroke length, not piston area. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100B Is Used
Machining Fixture Stops
Dial in the exact clamping extend position during setup-varying fixture changes on a CNC lathe without machining custom stop spacers.
Product Changeover Pushers
Quickly alter the extend end stop to accommodate different package sizes on a packaging line during rapid format changeovers.
Prototype Press End Points
Safely test and incrementally adjust trial end positions on a laboratory press before finalizing the mechanical dimensions.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100B the Right Cylinder?
Selecting this 32 mm bore provides 402.1 N push force at 0.5 MPa. If your application requires less force, the next size down is a 25 mm bore offering 245.4 N push, while stepping up to a 40 mm bore yields 628.3 N push. A standard fixed-stroke ACQ32x80 is sufficient if your end position never varies. When ordering, confirm the 80 mm full stroke, 100 mm window, the male M14x1.5 rod thread, and whether you need the magnet option for sensor detection.
Quick checklist
- ✓ Need on-machine end-position tuning?
- ✓ Full stroke and adjust window (mm)
- ✓ Force at your working pressure
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the adjuster nut after setting the stop.
- check The stop limits the EXTEND stroke only.
- check Avoid side load on the short piston rod.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100B FAQ
The usable extend range is 0-80 mm, created by the 80 mm full stroke minus the 100 mm window. Force is identical to a standard ACQ: 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The retract stroke is unaffected.
An external M12x1.25 threaded stop screw with a lock nut limits the extend distance, changing stroke length only without altering force. A fixed elastomer bumper decelerates the piston near the end. This plain cylinder does not hold the load if air is lost; use an external rod lock or pilot-operated check valve for fail-safe holding.
